In terms of earnings: TL. However they suck in like every game but dota 2 and they are in like every esports game they can apply.
But it pretty much comes down to FNC and G2. FNC are the only non asian team to win worlds and getting second in 2018, 2 masters, and a major. While doing that they were very consistent, always being in the top of thier region and quallifying to most international events. However FNC have been a bit off lately so that can be taken in account.
G2 I think have the most potential while being successful. Their accolades are ok as they never won worlds, a major, or a masters/champs. They have pretty good tho with a second in worlds, multiple blast finals and IEMs, and the acenssion trophy if we count that. But They have a lot of potential with their CS and Val rosters. They have one of the best opers in the world (m0nesy) and a very strong val team. G2 is very sucsessful in the RL scene so there is that to account for.
If I had to pick one, it would be FNC but I do think G2 will catch up
